The fact that Google launched a 7" tablet by ASUS isn't a particularly huge surprise, given that ASUS showed off the Eee Pad Memo back at CES. The story goes that Google liked that particular tablet so much, it became slotted in to become the first Nexus tablet, much to Samsung's chagrin. While there have been other "Google Experience" tablets before (for example the Motorola Xoom), there hasn't been a bona-fide Nexus tablet yet, and especially not one at an aggressive price point like this. For that, enter the Nexus 7.

The Nexus 7 comes with Android 4.1 Jelly Bean installed, which we're going over on the next page. It brings improvements to UI performance through Android

Most important is the Nexus 7's price point, which up until now has largely been one of the main issues with Android tablets - price. It's fair to say that the Kindle Fire has done a good job proving that there is indeed a market for lower cost, simplified tablets at an aggressive price point, and the Nexus 7 is Google's answer. Pricing for the Nexus 7 is $199 for the 8 GB model, and $249 for the 16 GB model. There aren't any other differences between the two, nor is there a model with cellular connectivity – this is strictly WiFi only, but again, this is a tablet for the masses without the carrier hurdle.

When you look at the above specs, it seems puzzling that ASUS was able to get the price down to $199 so effectively. Getting to that lower price point is easier with a few things - physically smaller device and display, exclusion of full size USB or other ports (there's only microUSB), no rear facing camera, and good commodity component sourcing. The added plus is that if you run 1280 x 800 at a smaller size, out comes a pretty high DPI panel at the same time. Other than that though, you end up getting a device which is actually very impressive otherwise, with a quad core SoC and attractive form factor.

I like starting with physical impressions since it's the easy route, and so much of one's experience with a given device depends on that ever important in-hand feel. ASUS has taken an excellent direction here and made the back construction of the Nexus 7 a great textured rubber material. There's Nexus embossed in the top, and ASUS proudly at the bottom. Below that is a small notch for the speaker, which goes pretty loud.

The power / lock and standby buttons get placed on the top right corner, and both microUSB and the headphone jack are located at the very bottom. There are also some pogo pins on the bottom left, just like the Galaxy Nexus. No doubt these will work with some future unannounced accessories.

The Nexus 7's construction is downright impressive. While I haven't been doing regular tablet reviews (that has become Anand's domain largely), I have handled a number of recent tablets big and small, and some feel downright cheap to me thanks to the back plastic. I would not have guessed that the Nexus 7 is a $199 device based on how it feels. There's no flex or creaking at all, it feels absolutely rigid. The tradeoff is that the Nexus 7 is slightly thicker than some other devices, at almost 10.5 mm (compared to 8.5 or 9), but that larger thickness also permits a bigger edge bevel radius. I feel that 7" is an ideal tablet form factor for me personally.

So the next logical question is what performance is like on the Nexus 7. I asked around, did my own digging, and wound up confirming that what's inside the Nexus 7 is indeed a Tegra T30L SoC. This is a lower leakage / lower binning T30 that no doubt is offered at a cost advantage to ASUS - I was expecting a T30L inside and am wholly unsurprised to see one. The only difference is that CPU clocks are 1.15 GHz for all four cores at 100%, or 1.3 GHz on a single core. The GPU clock is also slightly lower at 416 MHz. The Nexus 7 also ships with 1 GB of RAM, and I'm pretty certain this is DDR2 at 500 MHz based on what I see from the digging I've done.

I've borrowed Anand's TF700T review graphs and added data from the Nexus 7 that I hastily ran this afternoon. The results are in line with my expectations for T30L and other devices with T30L inside that we've already benchmarked.

The Transformer Pad 300 uses the same T30L SoC as the Nexus 7, so it isn't surprising to see the two post numbers very close to each other in so many places.

I should note on the browser synthetics that we're also talking about Chrome here, not "Browser" as the Nexus 7 is the first Android device to ship with Chrome as the default browser. In this case, that means there's no "browser" to be found anywhere on the device. You can still install Flash from the Play Store, it just doesn't do anything anymore.

Speaking of digging, I sent Francois Simond (@supercurio) a voodoo report from the Nexus 7, and he has graciously done a component analysis just like we've done with other devices in the past. There aren't too many surprises inside. WiFi and Bluetooth is courtesy the ever-ubiquitous BCM4330 module, which no doubt has gotten cheaper now that BCM4334 is out. The front facing camera is a Aptina MI 1040 1.3MP CMOS with 3.6µm pixels and 1/3" optical format. NFC comes courtesy a new NXP PN65 controller which is best I can tell a PN544 with embedded SE (secure element).

The next question is what that display looks like. We've seen other lower cost tablets ship before, but usually the first thing that gets skimped on is the display. In the case of the Nexus 7, ASUS notes that the panel is an LED backlit IPS panel with 10 point multitouch and 400 nits maximum brightness. Resolution is of course WXGA (1280 x 800) at 7". If you do the math out, that's a pretty high PPI, and in person it looks great - I can't see pixels unless I look very closely.

Since I expected having to do something of a tablet review on this trip to Google I/O, I brought along my i1D2 colorimeter. I took measurements on the Nexus 7 using my normal workflow – a combination of Francois' Voodoo Screen Test Patterns and Color HCFR.

Brightness falls a bit short of the advertised 400 nits at just 312 nits. I'm actually not sure whether there's some of Nvidia's Prism power saving tech going on here (there's no toggle anywhere for it), but that's as bright as I could get the Nexus 7 to go. Contrast on the other hand is pretty good, at 850, and blacks are very good at 0.37 nits.

The rest of the display metrics are a bit interesting, with color temperature hovering around 5500K which is a bit warm for my taste, and gamma isn't flat over the grey scale either. What's really curious to me is that the greens seem undersaturated (the larger triangle is sRGB), which was my first impression on seeing the Nexus 7 while installing some apps from Google Play (which has lots of green). Again I'm not sure whether this is some power saving Prism technique at work here.

I feel like those metrics could mislead you into thinking the display is bad, on the contrary it's obvious this is an IPS panel based on the viewing angles, which are superb off axis in the horizontal and vertical. You just can't get away with putting a TN in a tablet because of how bad viewing angles are immediately visible on a big surface device like a tablet. The Nexus 7's IPS display is very contrasty and has a high enough PPI that I'm not wishing for higher resolution.

Google is also doing something interesting with the Nexus 7 by bundling a $25 Play Store credit which pops up in your account after signing into your Google account for the first time. The strategy seems pretty obvious here - get Nexus 7 buyers to at least check out the Play stores. In addition, they've preloaded a number of books and videos which should bait users into at least checking out the respective Google Play applications.

Honestly I think ASUS and Google have really done an excellent job here with the Nexus 7. The combination of a quad core SoC, IPS panel, solid construction, and the latest version of Android all for such a killer price point pretty much make it hard to really find any faults. Sure, it'd be useful to have a full size USB host port, microSD slot (though no Nexus has shipped with one since Nexus S), 5 GHz WiFi (Nexus 7 is 2.4 GHz only), or cellular, but the tablet wouldn't be $199 anymore. I also really feel like the 7 inch diagonal form factor is an ideal one, and the Nexus 7 is quickly growing on me.

Update: I've had many emails and questions about whether USB-OTG (On The Go) is supported on the Nexus 7, and didn't touch on it when I originally hit publish becuause I wasn't entirely sure. I've now confirmed that USB-OTG is supported on the Nexus 7, and works on the current Android 4.1 non-final build that has been sampled. That's encouraging, and I'll test it myself when I get home and to my miniUSB OTG adapter.

Update 2: I've asked for further clarification about what USB-OTG functionality is supported. Using a mouse and keyboard will be supported, and I saw Google using an ethernet to USB adapter over USB-OTG as well. Unfortunately I found out that mounting USB storage will not be supported natively. In addition MHL is not supported.

Also, there's no way that Asus would agree to build this, if they weren't making any money. Again, take the whole product down and the bill of materials is undoubtedly below $200. $199 is likely what Google is paying per device. But Asus isn't breaking even on this. They're making a profit because the total cost of components is less than this, possibly much much less. And OEMs can do the same. And better than that, they can start stratifying based on honest to goodness features. Want a better display? Charge more. Want it bigger? Charge more. Want more memory? Charge more. Want more processor? Charge more. We know from the PC space that the BOM for a low specced device is not that far off from a higher specced device. But when you order a Dell with lots more memory, the fee is ever larger, and far outpaces the cost of the actual RAM. This establishes how that same model can be applied to tablets.Reply

Don't think of this as an effort to harm OEMs, nor even to move units. Popularity would help move the conversation along, but what this does is establish a standard that all OEMs should work with.

Want to sell a $200 tablet, it should be this good. Want to go downmarket, make sure you're experience isn't so crappy that people regret it and wish they'd bought this. Want to go upmarket, make sure you offer enough features and performance boost to make it a compelling offer.

Without establishing this sort of base-line, you had mainstream tablets priced from $200 to $600, and though feature sets were all over the place, performance wasn't nearly so varied. NVIDIA knows how to stratify products, so they've done a great thing by providing the same part at different bins. But the SoC isn't close to the most expensive portion of the bill of materials for any tablet. That goes to the display, and depending on the capacity and density the NAND.

If you're an OEM, you're thinking, ok, I can make money on this by just adding a camera, or using the same other components but using the top binned Tegra 3, which would incrementally raise the BOM, but I could then charge $100 more.

The Nexus 7 establishes the roadmap by which OEMs can charge reasonable prices and still make money, and it sounds like Jelly Bean is what makes all of that possible. Reply

Brian, i appreciate your and Anand reviews as the best on the net but i notice one deficiency again and again. Please check your eyes and in future for all reviews wear at least +1 or +1.5 reading glasses. Check them for astigmatism too. The 200ppi is NOT acceptable for anything besides laptops and large monitors. Plus you must always keep your cell phones and small screen size tablets at the ***average best viewing distance*** for normal 20/20 vision which always for centuries was 25 cm or 10" not 12" as Steve Jobs "reinvented" it for marketing reasons or also had vision problems. Larger tablets keep at 12" and superlarge at 15". The laptops and monitors you may keep at SMPTE (30 degrees horiz angle) or better at THX recommended viewing distance (36 degrees) or even closer if monitor has better ppi.Reply

I own 7" Hyundai A7HD tablet with mini sd, and mini HDMI. It is not as powerful as Google's Nexus but connected with wireless keyboard and mouse and my 26" Benq monitor, I could use it daily as full blown PC.

It is pity with Google Nexus 7 even with powerful quad core cpu I could not connect with my monitor .Reply
